Twenty-three people will die from suicide today in South Africa. Another 460 South Africans will try to end their lives today. They are from different cultural groups, different income groups, attained different levels of education, speak different languages, range in age from childhood through to elderly, have different genders and sexual orientations. These people have very little in common except that their lives all ended due to the final symptom of an illness. People who experience thoughts of ending their lives describe this mental space as feeling grey. Their thoughts tend to keep returning to the futility of being alive, what a burden they are to those around them, how nothing will ever get better and that nobody can help them. They tend to experience feelings of worthlessness, self-hatred, guilt, hopelessness, immense sadness and despair. Their suffering and emotional pain are excruciating. Nothing is enjoyable anymore. There is nothing to look forward to. Everything is difficult, boring, scary or meaningless. Inwardly they are drowning. But very often they smile, do their job and pass their exams, go on dates and vacations, make plans for the weekend and check up on their loved ones. They look happy in their photos. And when someone asks them if they are okay they say yes. Because they don’t feel like they deserve to feel better. They don’t want to be a bother. They might not call a helpline or make an appointment to see a psychologist or go to their GP for anti-depressants. Because they just don’t have the energy. It’s exhausting pretending to be fine all day. The one thought that brings relief is that they can end this pain. And one day they do. And their colleagues, friends and family are left reeling with shock and disbelief. How could this have happened? How could they have missed the signs? What should they have done differently to prevent this? 

The causes are as complex and varied

This is the purpose of World Suicide Prevention Day which takes place internationally each year on 10 September and through which the International Association for Suicide Prevention endeavours to increase awareness of suicidality, as well as to fight the stigma associated with suicide. Wanting to die can occur along with many other symptoms and disorders including, but not limited to, depression, post-traumatic stress disorder, bipolar disorder, psychotic disorders, personality disorders and substance dependence or abuse disorders. The causes are as complex and varied as the manner in which suicidality may present. It is dangerous to regard only certain signs and symptoms as indicative of suicide risk, because we know that suicide can be extremely unpredictable. There is no way to tell if someone is a suicide risk based purely on their behaviour. However there are certain factors which may indicate an increased risk for self-harm. These include, but are not limited to, having previously tried to end their life, having a psychiatric illness, being seriously ill or having chronic pain or the misuse of substances. Experiencing legal, relationship, financial or academic stressors may increase suicide risk, as well as having access to lethal means to end their life along with being unable to access mental health care. 

So what can you do if you think someone may be at risk of self-harm? Say something. Talk to them. Tell them what you are worried about and give them the space to express how they feel without judgment or condemnation. Reach out to their support system and share your concerns with them. Encourage the suicidal person to make contact with a health care professional – this can be a psychologist, GP, psychiatrist, social worker, psychiatric nurse, counsellor or a suicide prevention help line. Other important members of our community who provide a great deal of assistance to suicidal people and their families include religious and spiritual leaders, teachers, support groups and employee assistance programmes. There are actually so many ways and places to receive health care and support; however the most significant barrier to making use of these resources is sustained by the stigma associated with suicide and mental illness. In our culture of toxic positivity where our photos are touched up, our statuses updated and our successes plastered on various social media platforms, the authentic act of acknowledging when we feel defeated, unhappy or like a failure has become a rarity. The more real, honest and vulnerable we can be about our ‘undesirable’ emotions and experiences, the more space we create for those around us to do the same. When we normalise not being okay at all times, we give ourselves and others permission to speak up when we need help. And this is our greatest weapon against suicide – authentic connection.

What suicide is not

We’ve explored what it may feel like to be suicidal, now let’s focus on what suicide is not. Suicide is not a moral failing. It is not because the person was weak or selfish, it is not because their family was dysfunctional or their faith not strong enough. Suicide is the final symptom of mental illness – and every single person is vulnerable to experiencing suicidal thoughts. Each one of us will be affected by suicide during the duration of our lives, either directly or indirectly. This is irrespective of how successful you are, how supportive your family is or how strong your religious convictions are. Dying by suicide is not a shame. It is not a failure. It is no different to a patient dying from any other disease. And just like any other illness there are symptoms we can look out for and treatments and medications that can assist in recovery. 

Please think before you speak about someone who died due to suicide. I guarantee that at least one person in the conversation has suffered the pain of losing someone in this way. But you probably wouldn’t even know, because stigma silences. Stigma disconnects and alienates those who need support the most. Our words have the power to shame and silence, or to empower and encourage connection, which is lifesaving. Treat each conversation as though there may be someone present who is having suicidal thoughts or is working through the loss of someone they love due to suicide. Often we want to reach out and support families affected by suicide, but don’t because we are afraid of offending, or upsetting or because we ourselves are so uncomfortable with mental illness. But all these survivors of suicide need from you is your calm, empathetic, kind presence, a safe space to express difficult and messy emotions. Without being blamed or shunned or shamed. Support suicide survivors as though a terrible illness took the life of their loved-one. Because that is exactly what happened. 

On 10 September this year I encourage you to light a candle and place it in your windowsill around 8pm wherever you are. This is in remembrance of those lost to mental illness and to show your support to those they left behind. In the words of the International Association of Suicide Prevention: “By encouraging understanding, reaching in and sharing experiences, we want to give people the confidence to take action. To prevent suicide requires us to become a beacon of light to those in pain. You can be the light.”

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
